Quick answer: This Round/Flat Bottom Flask is a versatile glass vessel used for heating, mixing, and containing liquids during distillation, reflux, and general chemical procedures. Flask, Round/Flat Bottom (Clear Glass) is priced at approximately ₹785 (indicative market benchmark, incl. GST, August 2026).
Round and flat bottom flasks are general-purpose glass vessels used to hold and heat liquids during laboratory procedures such as distillation, reflux, and synthesis reactions. A round-bottom flask distributes heat more evenly and withstands thermal stress better, making it suited to heated reactions, while a flat-bottom flask can stand upright on a bench without a support ring, making it convenient for simple mixing and storage tasks. Made from clear glass, this listing covers both bottom shapes — confirm with STEMAids which shape is included before ordering. It’s a standard piece of equipment in college and research chemistry laboratories.

Applications
- Distillation and reflux setups requiring a heated flask
- General mixing and containment of liquid reagents
- College and research chemistry laboratory practicals
- Standard glassware for building modular reaction assemblies
Care & Maintenance
- Use appropriate heating equipment (water bath, sand bath, or heating mantle) rather than a direct open flame
- Handle carefully — clear glass is more prone to thermal shock than borosilicate
- Clean thoroughly after each use to prevent residue buildup

Frequently Asked Questions
What’s the difference between round-bottom and flat-bottom flasks?
Round-bottom flasks distribute heat more evenly and handle thermal stress better, suited to heated reactions; flat-bottom flasks can stand upright without support, convenient for mixing and storage.
Which bottom shape does this specific listing include?
The exact bottom shape and capacity have not been independently verified for this listing — confirm with STEMAids before ordering.
Is clear glass suitable for direct heating?
Clear glass is less heat-resistant than borosilicate glass; confirm suitability with STEMAids before using with direct or high-temperature heating.
Is this suitable for a college chemistry teaching lab?
Yes — round and flat bottom flasks are standard equipment for distillation, reflux, and general practicals in chemistry coursework.
Does STEMAids supply a borosilicate version for heated applications?
Contact STEMAids to confirm current availability of borosilicate flask options.
Is STEMAids a registered manufacturer of this product?
Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
